Popis: | Optimizing the removal of solid sebum soil appears to depend on both the surfactant and the soil substrate. Like other solid, organic soils, sebum’s removal from hard surfaces involves penetration of the surfactant (and associated solvent molecules) into the soil. This soil-softening (liquefaction) process prepares the soil for secondary processes (roll-up, abrasion, emulsification, etc.) which accomplish soil removal. A smaller hydrophobe and lower HLB both appear to aid soil removal by increasing surfactant penetration into the soil. However, when solid sebum is present on cloth, the ability to wet the cloth matrix becomes important. Surfactants better able to promote cloth wetting appear to be better at penetrating the soil, because wetting increases the amount of surfactant in contact with the soil. |
